The heat exchanger is provided with a housing body (1); wherein, an inlet and an outlet of a medium are respectively and oppositely provided on the parts of the housing body (1) close to the two ends. Two pipe plates (4) are respectively provided on the two ends of the housing body (1). The utility model is mainly characterized in that the bead form condensing heat exchangers (2) are provided on the heat exchanger in axial direction and in parallel; the two ends of the bead form condensing heat exchanger tube (2) are respectively and vertically connected with the two pipe plates (4); the bead form condensing heat exchanger tubes (2) are arrayed in parallel and in bunch form; sector-form transverse baffles (3) distributed in helix type are provided between the inlet and the outlet of the medium. The heat exchanger has the advantages of high effective heat conduction performance, non-heat transfer dead zone, non-low pressure performance, self-cleaning function, compact structure and small occupying area.
Description
Technical field the utility model relates to a kind of improved heat exchanger, refers in particular to a kind of helical baffles dropwise condensation heat transfer pipe pipe bundle heat exchanger, should be divided into the F28D group in International Patent Classification (IPC).
Background technology is present, in order to improve the heat exchange efficiency of heat exchanger, has adopted various forms of heat exchangers.For example the light pipe heat exchanger tube is improved to the corrugated tube heat exchanger tube bank, makes medium fully disturbance in bellows, destroyed inside and outside boundary layer preferably, improved heat exchange efficiency; But this heat exchanger deflection plate still is original segmental baffle, although heat exchange efficiency has improved, but the pressure loss is big.In order to reduce the pressure loss, I have invented helical baffles corrugated tube bundle heat exchanger, the patent No.: ZL01259436.9, May 1 2002 Granted publication day.Medium in housing continuously, steadily, rotating mobilely, avoided the catadioptric pressure loss of bringing of wide-angle, reduced energy consumption; But the ripple tube wall is thin, and the scope of application is little, and corrugated tube bundle forms the continuous film of condensate on heat exchange surface, and the effect of membranaceous heat transfer is influenced.Heat exchange efficiency changes little.
The summary of the invention and specific embodiment goal of the invention of the present utility model is to provide a kind of and overcomes the deficiency of above-mentioned heat exchanger and the not heat transfer dead band of spiral baffle heat exchanger and the efficient heat-conductive characteristic of low pressure drop performance and dropwise condensation (dropwise condensation) heat exchanger tube are combined, and produces a kind of new type high efficient heat exchanger.
The purpose of this utility model is achieved through the following technical solutions: described helical baffles dropwise condensation heat transfer pipe pipe bundle heat exchanger has a housing (1), part at the close two ends of described housing (1) is oppositely arranged advancing of medium respectively, outlet, two ends at described housing (1) are provided with two tube sheets (4) respectively, main feature is: the axially parallel at described heat exchanger is provided with dropwise condensation heat transfer pipe (2), the two ends of described dropwise condensation heat transfer pipe respectively with vertical connection of described two tube sheets (4), being arranged in parallel between the dropwise condensation heat transfer pipe (2) is pencil; The segmental baffle (3) of spiral distribution is set between the import and export of described medium.Described spiral is single, double spiral.Described dropwise condensation heat transfer pipe (2) is nickel-base seeping layer pipe, acid bronze alloy pipe.Described heat exchanger comprises distance sink tube (6), described distance sink tube (6) the periphery of two end respectively with vertical connection of segmental baffle (3).Described heat exchanger comprises backstay (5), and described backstay (5) passes described distance sink tube (6), the two ends of described backstay (5) respectively with vertical connection of tube sheet (4).Every segmental baffle (3) has an angle of inclination.Described housing (1) is a metal shell.The used metal of described housing (1) is carbon steel, stainless steel.
Below in conjunction with drawings and Examples the utility model is further specified, wherein:
Accompanying drawing 1 is the schematic diagram of helical baffles dropwise condensation heat transfer pipe pipe bundle heat exchanger structure.
Accompanying drawing 2 is helical baffles dropwise condensation heat transfer pipe pipe bundle heat exchanger operation principle schematic diagrames.
From accompanying drawing 1, can be clear that the primary structure of helical baffles dropwise condensation heat transfer pipe pipe bundle heat exchanger: housing (1), dropwise condensation heat transfer pipe (2), segmental baffle (3), tube sheet (4), backstay (5), distance sink tube (6).
Can further see from accompanying drawing 1: be oppositely arranged the import and export of medium at described housing (1) respectively near the part at two ends, one on the upper left side, and one in the lower right.Two ends at described housing (1) are provided with two tube sheets (4) respectively.Main feature of the present utility model is: the axially parallel at described heat exchanger is provided with dropwise condensation heat transfer pipe (2), the two ends of described dropwise condensation heat transfer pipe respectively with vertical connection of described two tube sheets (4), being arranged in parallel between the dropwise condensation heat transfer pipe (2) is pencil.The segmental baffle (3) of spiral distribution is set between the import and export of described medium, and its segmental baffle (3) has an angle of inclination.Can also further see from accompanying drawing 1: this heat exchanger also comprises distance sink tube (6), described distance sink tube (6) the periphery of two end respectively with vertical connection of segmental baffle (3), to guarantee the designed distance of segmental baffle.Described heat exchanger comprises backstay (5), and described backstay (5) passes described distance sink tube (6), the two ends of described backstay (5) respectively with vertical connection of tube sheet (4), to guarantee the location of segmental baffle.
Experimental results show that and the utlity model has following advantage:
Because deflection plate is in spiral distribution, medium in housing continuously, steadily, rotating mobilely, do not pass Hot dead band and low pressure drop performance have improved heat transfer coefficient.
Dropwise condensation (dropwise condensation) heat exchanger tube be adopt nickel-base seeping layer pipe and acid bronze alloy pipe good heat conductivity, The little Metal Mechanic Property of thermal resistance and anti-corrosive properties are strong, are mainly used in the industry such as petrochemical industry, thermal power generation and metallurgy Department. This heat exchanger has self-cleaning action, compact conformation, and floor space is little, is complex heat transfer efficient height Heat exchanger.
